The elevator IQ-and the platform l8*are prey videdswith an-endl'ess conveyor 24 operatingover 150 sprockets 2 5 mounted on ashaft 28; which in turn is mounted on -the frame members ID, the

outer endof the shaft 26 being provided with-a sprocket 21' The frame -members', lll arejpro sprockets 21 1 and-'2 s bein'gprovided with a'" chain shaft 28 by means of mitre gears 42.

30. The frame member I4 is provided with bearings 3| and 32 rotatably supporting a drive shaft 33 having its rear end provided with a belt pulley 34, the shaft 28 having a belt pulley 35, said pulleys being rotatably connected with a twisted belt 36. The forward end of the shaft 33 is provided with a squared portion 31 adapted to receive the coupling device connected with the power take-off shaft of the farm tractor to which the member I4 is connected. Thus means is provided for driving the conveyor 24 by the shaft 33 by means'of the belt 36 and the chain 36.

For delivering material to the platform I 8 I have provided what I shall term a gathering platform 38 pivotally supported on a shaft rotatably supported in bearing members 39 carried by the forward one of the frame members I8. The shaft 40 has one end extended into a gear box 4| and operatively connected with the conveyor 43 is mounted on the platform 38 adapted to travel over sprockets 44 fixed to the shaft 40 and around sprockets 45 mounted on the shaft 46 at the lower end of the platform 38. Below and forwardly of the shaft 46 is a tubular bar 41 having a series of upwardly extending supports 48, the upper end of each of said supports 48 being provided with a downwardly and forwardly extending tine 49, the forward ends of the tines terminating in the contractedportions 50, the members 49 being preferably in the form of an angle iron with its flanges supported at an angle of 45 relative to the bar 41, as illustrated in Figure 6. The back ends of the members 49 are supported substantially in a plane common to the upper surface of the platform 38 in such a manner that as the tines are advanced over the ground surface in the inclined position substantially as illustrated in Figures 2 and 7, the portions 50 will enter beneath the material to be loaded. This said material is crowded rearwardly and upwardly and slid along the top of the member 49 to the conveyor 43, so that the material is supported above the cross bar 47 to such an extent that it does not drag on the bar to hold the material against its-upward and rear ward movement, the material being supported above the bar 41 substantially as illustrated in Figure 6. This provides means whereby the ma terial may be delivered to the gathering platform 38 without any additional gathering devices.

For maintaining the free ends of the tines 53 elevated above the groundsurface at such times as the machine is being advanced from one shock to another, and to provide means wherein said tines may be easily and quickly lowered to operative position, and further to provide means whereby the tines may be normally maintained against the ground surface at such times as the device is being used to gather hay and the like, I have provided the following mechanism: On the under surface of the members In I have provided forwardly extending frame members 5| having at their forward ends a rock shaft 52. On each end of the rock shaft 52 I have provided a forwardly extending rock arm 53, the forward end of each of said arms 53 being pivotally connected to the lower end of an upright extension spring 54, the upper end of which is supported by a bracket 55 carried by the side members 56 of the platform 38. A nut 51 is mounted on the upper end of a shaft 58 extending through said spring and provides means for limiting .the upward movement of the platform 38 relative to the rock arms 53. By this arrangement it will be seen An endless that the weight of the forward end of the gathering platform 38 is carried by the yieldable springs 54. A lever 59 is provided for adjusting the rock shaft 52 by means of a link 60 and an upright member 6| carried by one of the rock arms 53. If the upper end of the lever 59 is moved forwardly then the forward ends of the rock arms 53 are lowered, causing the springs 54 to be lowered, and in turn the tines 49. However, if it is desired to maintain the tines in an elevated position, the lever is set in the position illustrated in Figure 4.

Carried by the member I 5 and one of the members 5| is a rock shaft 62 having a crank 63 on one end to which a crank 64 is connected, which in turn is connected to one of the side members 56. A rock arm 65 is mounted on the opposite end of the shaft 62 to which a rod 66 is connected, the forward end of which is preferably connected to a foot pedal 61 which may be mounted on the tractor to which the member I4 i attached.

When it is desired to lower the forward end of the tines 49 when gathering shocks the upper end of the pedal 61 is moved forwardly, causing the shaft 62 to be rocked, the link 64 lowered and the forward end of the platform 38 lowered against the tension of the springs 54. By this arrangement it will be seen I have provided a shock loader which may be utilized to gather and elevate material directly from the windrow in a continuous manner or may be used to gather shocks spaced apart aconsiderable distance, the lever being converted from a shock gatherer with the tines formed in the position shown in Figure 4, to position for gathering material from the windrow in a continuous manner, as illustrated in Figure 2, by simply moving the lever from the dotted line position in Figure 2 to the solid line position.

In operation the device is advanced with the material being carried on to the gathering platform 38 for movement by the conveyor 24 to the platform l8 and on top of the conveyor 24 and then elevated and delivered over the upper end of the section 26, to a suitable wagon or other conveying means.

It will further be seen that I have provided in a hay and shock loader an improved tine construction used in connection with a gathering conveyor wherein the material may be sufliciently delivered to the gathering conveyor without obstruction or clogging.

It will further be seen that I have provided a shock loader of comparatively simple, light and cheap construction which may be easily and quickly attached to the ordinary farm tractor and in which is employed a verysimple and eflicient means for delivering power from the tractor to the gathering and elevating conveyors.

I claim as my invention:
